Adolescents' risky behavior and mass media use.

OBJECTIVE: To understand better the relationship between adolescents' use of the mass media (including television, radio, and magazines) and their risky or unhealthy behaviors. DESIGN: Secondary data analysis of a 1987 in-home survey of 2760 randomly selected 14- to 16-year-old adolescents in 10 urban areas in the southeastern United States. MEASUREMENT: The extent of participation in eight potentially risky behaviors (sexual intercourse, drinking, smoking cigarettes, smoking marijuana, cheating, stealing, cutting class, and driving a car without permission) and the use of a variety of mass media. RESULTS: Adolescents who had engaged in more risky behaviors listened to radio and watched music videos and movies on television more frequently than those who had engaged in fewer risky behaviors, regardless of race, gender, or parents' education. White male adolescents who reported engaging in five or more risky behaviors were most likely to name a heavy metal music group as their favorite. Adolescents reported reading a wide diversity of magazines, and most reported reading at least one of a few selected magazines. Sports and music magazines were most likely to be read by adolescents who had engaged in many risky behaviors. CONCLUSIONS: Mass media health promotion efforts could more specifically target adolescents who are engaging in multiple risky behaviors.

Relation of peer and media influences to the development of purging behaviors among preadolescent and adolescent girls.

OBJECTIVE: To assess prospectively the relation of peer and media influences on the risk of development of purging behaviors. DESIGN: Prospective cohort study. SETTING: One year follow-up of 6982 girls aged 9 to 14 years in 1996 who completed questionnaires in 1996 and 1997 and reported in 1996 that they did not use vomiting or laxatives to control weight. MAIN OUTCOME MEASURE: Self-report of using vomiting or laxatives at least monthly to control weight. RESULTS: During 1 year of follow-up, 74 girls began using vomiting or laxatives at least monthly to control weight. Tanner stage of pubic hair development was predictive of beginning to purge (odds ratio [OR] = 1.8; 95% confidence interval [CI], 1.3-2.4). Independent of age and Tanner stage of pubic hair development, importance of thinness to peers (OR = 2.3; 95% CI, 1.8-3.0) and trying to look like females on television, in movies, or in magazines (OR= 1.9; 95% CI, 1.6-2.3) were predictive of beginning to purge at least monthly. Regardless of the covariates included in the logistic regression model, the risk of beginning to purge increased approximately 30% to 40% per 1-category increase in frequency of trying to look like females on television, in movies, or in magazines. CONCLUSIONS: Both peers and popular culture, independent of each other, exert influence on girls' weight control beliefs and behaviors. Therefore, to make eating disorder prevention programs more effective, efforts should be made to persuade the television, movie, and magazine industries to employ more models and actresses whose weight could be described as healthy, not underweight.

Cultural expectations of muscularity in men: the evolution of playgirl centerfolds.

OBJECTIVE: We sought to assess whether cultural ideals of the male body, as illustrated by magazine models, have changed over the past 25 years. METHOD: We examined 115 male centerfold models in Playgirl magazine from 1973 to 1997. Using the models' heights and weights quoted by the magazine, together with visual estimates of body fat, we calculated the body mass index (BMI) and fat-free mass index (FFMI) of each model. RESULTS: The Playgirl centerfold models became increasingly "dense" and more muscular over time, as indicated by the significant correlations between BMI, FFMI, and year of publication. DISCUSSION: These observations, in combination with previous studies, suggest that cultural norms of the ideal male body are growing increasingly muscular.

News & notes: paper digestion by the cellulolytic ruminal bacterium Fibrobacter succinogenes.

The objective of this study was to evaluate the ability of the predominant cellulolytic ruminal bacterium Fibrobacter succinogenes S85 to digest filter paper, office paper, newspaper, and magazine paper. When F. succinogenes S85 was incubated with all four paper sources, little digestion of any paper occurred between 0 and 48 h. However, digestion of filter paper increased from 12% at 48 h to 80% at 120 h. No significant digestion of office paper, newspaper, or magazine paper occurred between 48 and 120 h. These results suggest that F. succinogenes S85 is unable to digest office paper, newspaper, or magazine paper.

Natural reward-related learning in rats with neonatal ventral hippocampal lesions and prior cocaine exposure.

RATIONALE: Psychostimulant injections in rats have been shown to alter future performance in natural reward conditioning. These effects may represent a persistent impact of drugs on neurocircuits that interface cognitive and motivational processes, which may be further altered in neuropsychiatric conditions that entail increased addiction vulnerability. OBJECTIVE: This study investigated whether a rat model of schizophrenia with cocaine addiction vulnerability shows altered natural reward conditioning with or without prior cocaine exposure. METHODS: Adult rats with SHAM or neonatal ventral hippocampal lesions were given cocaine (15 mg/kg per day for 5 days) or saline injections, followed 7 days later by natural reward-conditioned learning. Over ten daily sessions, water-restricted rats were assessed for durations of head entries into a magazine during random water presentations, a conditioning stimulus phase predictive of the water reward, and an "inappropriate" phase when conditioning stimuli were absent and reward presentation would be delayed. RESULTS: Over repeated sessions, lesioned and SHAM rats showed similar reductions in total magazine entry durations, with similar increases in the allocations of entry times during the water presentation. However, lesioned rats, especially those exposed to cocaine, demonstrated reduced allocations of magazine entry times during the conditioning stimulus phase, and increased allocations during the inappropriate phase. CONCLUSIONS: Intact natural reward motivation accompanied by deficient learning of complex contingencies to guide efficient reward approach may represent a form of impulsivity as an addiction vulnerability trait marker in an animal model of schizophrenia.

Mechanism of action of 8-OH-DPAT on learning and memory.

It has been previously demonstrated that pretraining injection of 8-hydroxy-2-(di-n-propilamino)tetralin (8-OH-DPAT, a 5-HT1A agonist) impairs conditioned response (CR) in an autoshaping learning task. Therefore, in the present work we intended to determine whether such an effect could be prevented by pretraining, and whether pre- or postsynaptic 5-HT receptors are involved. Groups of rats received or did not receive food magazine training. On the next day, all groups in both conditions, pre- or posttraining, were treated with 8-OH-DPAT (0, 0.062, or 0.250 mg/kg). Posttraining groups were tested on a second session of autoshaping 24 h later. In a second experiment, naive rats received para-chlorophenylalanine (PCPA) (300 mg/kg x 3 days) before pre- or posttraining injection of 8-OH-DPAT. Results showed that in those groups trained to food magazine and treated 24 h later with 8-OH-DPAT, CR was not affected or enhanced. PCPA injection had no effect by itself, but blocked or attenuated the effect of a post- or pretraining injection of 8-OH-DPAT. The present data suggest that a) the pretraining effect of 8-OH-DPAT eliciting a decrease in CR can be eliminated by a food magazine training session; and b) presynaptic 5-HT1A receptors are involved in the effect of 8-OH-DPAT on the acquisition and consolidation of learning.

Consumer attitudes about advertisements for medicinal drugs.

Approximately 1500 subjects were exposed to magazine or television advertisements for fictitious prescription drug products. The ads varied the way risk information was incorporated into the ad. Ads presented in the magazine, ads that contained detailed and specific descriptions of the drug's risks, and ads that used communications devices to emphasize risks (graphic subtitles or a separate announcer to read the risk material) were negatively evaluated. Television ads were more likely to lead subjects to state that they would consult a doctor about the medicine but not to be upset if the doctor refused to prescribe it. Evidently, television produced more positive but more tentative impressions about the product compared to the magazine. General risks informing people about the importance of the doctor in making prescribing decisions appeared to be reassuring. Older subjects had more positive views of the drug and the ad, were more receptive to the doctor's advice and were more concerned about the disease. The elderly may have viewed drugs as a symbol of health, whereas, younger subjects may have viewed them as a symbol of illness.

Evidence for a neural correlate of a framing effect: bias-specific activity in the ventromedial prefrontal cortex during credibility judgments.

BACKGROUND: Neural processes within the medial prefrontal cortex play a crucial role in assessing and integrating emotional and other implicit information during decision-making. Phylogenetically, it was important for the individual to assess the relevance of all kinds of environmental stimuli in order to adapt behavior in a flexible manner. Consequently, we can in principle not exclude that environmental information covertly influences the evaluation of actually decision relevant facts ("framing effect"). OBJECTIVE: To test the hypothesis that the medial prefrontal cortex is involved into a framing effect we employed functional magnetic resonance imaging (fMRI) during a binary credibility judgment task. METHODS: Twenty-one subjects were asked to judge 30 normalized news magazine headlines by forced answers as "true" or "false". To confound the judgments by formally irrelevant framing information we presented each of the headlines in four different news magazines characterized by varying credibility. For each subject the susceptibility to the judgment confounder (framing information) was assessed by magazine-specific modifications of the answers given. RESULTS: We could show that individual activity changes of the ventromedial prefrontal cortex during the judgments correlate with the degree of an individual's susceptibility to the framing information. CONCLUSION: We found (i) a neural correlate of a framing effect as postulated by behavioral decision theorists that (ii) reflects interindividual differences in the degree of the susceptibility to framing information.

Mass media as a sexual super peer for early maturing girls.

PURPOSE: To investigate the possibility that the mass media (television, movies, music, and magazines) serve as a kind of super peer for girls who enter puberty sooner than their age-mates. Multiple studies have demonstrated significant associations between earlier pubertal timing and earlier transition to first sex. Does puberty also stimulate interest in sexual media content that is seen as giving permission to engage in sexual behavior? METHODS: White and African-American female adolescents (n = 471; average age 13.7 years) recruited from public middle schools in central North Carolina completed two self-administered surveys in their homes about their pubertal status, interest in and exposure to various media, and perceptions of sexual media content. RESULTS: Earlier maturing girls reported more interest than later maturing girls in seeing sexual content in movies, television, and magazines, and in listening to sexual content in music, regardless of age or race. Earlier maturing girls were also more likely to be listening to music and reading magazines with sexual content, more likely to see R-rated movies, and to interpret the messages they saw in the media as approving of teens having sexual intercourse. CONCLUSIONS: The mass media may be serving as a kind of sexual super peer, especially for earlier maturing girls. Given the lack of sexual health messages in most media adolescents attend to, these findings give cause for concern. The media should be encouraged to provide more sexually healthy content, and youth service providers and physicians should be aware that earlier maturing girls may be interested in sexual information.

A comparison of breast, testicular and prostate cancer in mass print media (1996-2001).

This paper compares the portrayal of breast, testicular and prostate cancer in mass print English language magazines in the United States and Canada from 1996 to 2001. It is a follow-up of three papers that examined each of these three diseases separately in high circulating magazines up to 1995. It includes both quantitative and qualitative analyses of magazine stories and notes the continuing dominance of a medical perspective regarding disease as well as the association of each type of cancer examined with stereotypically individualized yet feminine and masculine characteristics and pursuits. It notes the conflation of breast cancer, since the discovery of BRCA1 and BRCA2, with the family. To be a 'feminine' woman is to be vulnerable to breast cancer and to be a 'masculine' man is to be vulnerable to testicular cancer when young and prostate cancer when older. The association of disease not just with personhood but also with the specifics of stereotyped masculinity and femininity may construct a more intimate, more personal link between disease and identity. This close attachment of gender and disease may shore up and exacerbate a fear reaction. It may also serve to diminish the awareness of other, more prevalent, causes of death for men and women. The social control consequences of potentially exacerbated disease-specific fear are discussed.

[Adolescents and sources of sex information: preferences and perceived usefulness].

OBJECTIVES: To find adolescents' assessment of the information received at their school on questions relating to sexuality. To discover their main sources of information on sexuality, the perceived utility of these and their preferences. DESIGN: Observational study. SETTING: Province of Cordoba. MEASUREMENTS AND MAIN RESULTS: 955 adolescents at secondary schools were chosen through multistage randomised sampling. Anonymous health questionnaire. Average age was 16.62% were girls. 545 valued as a lot or sufficient the AIDS information received (57%; 54.3-59.6), more than when asked about STD (29%; 25.4-31.9), contraceptives (33%; 29.7-35.2), sexual relations (22%; 19.5-24.1) or pregnancy (22%; 19.3-24.2). They were able to talk openly about sexuality, firstly with friends (90.8%) and girl/boy-friend (80.5%), and least with teachers (18.7%), parents (17.4%) or priests (8.9%). Sexual information came basically from friends (26%) and magazines (24%), and least from doctors (7%) and parents (6%). The most useful source for adolescents was magazines (21%) and teachers (21%), with parents and cinema/T.V. in the last positions. When adolescents were asked from whom they would prefer to receive information, they chose firstly parents (34%) and doctors (33%). CONCLUSIONS: Adolescents perceived a centering of the information received at their school on AIDS. Their preferred sources of information did not coincide with what was most accessible. Despite considering doctors as a preferred source, they have received little information from us. The usefulness given to magazines is worthy of note.

[News about cancer in the press].

BACKGROUND: News on health and health care are increasingly common in the mass media, and cancer is one of the most prominent topic among these news due to its health impact. MATERIAL AND METHODS: All news published in major newspapers in Catalonia, Spain between April to December 1996 were analysed, together with items from science and health supplements general information and science journals. Types of cancer-related topics, sources of information, the importance of cancer in the news item and the theme of the piece were analysed. RESULTS: During the period analysed, 974 news items were published which dealt with cancer. Of these, cancer was the principal topic in 53.5% of the items published in the national press, and 63.4% of the items published in the regional press. Cancer was the subject of an editorial comment on only four occasions. The source of information was mentioned in 64.8% of the items, and mean number of sources was 1.6. Political institutions were the most frequent source of information in newspapers, while science and health supplements and other magazines tended to cite scientific and health care institutions, as well as scientific journals. Basic research was the most common topic for news (30.3%) in science and health supplements while risk and environmental factors (29.6%) were the most common topics in magazines; environmental and technological risk factors (18,6%) and conflicts with health administrative bodies (16%) were the most frequent topics in the newspapers. CONCLUSION: News about risk factors and their prevention as well as technological and environmental factors related to cancer were among the most important topics published in the general press and magazines, together with conflicts with administrative bodies. Informations related to new therapies were a less frequent topic. Scientific journals have an important role as an information source for mass media together with political and scientific institutions.

The social construction of the breast cancer epidemic.

The age-adjusted incidence of breast cancer among U.S. women rose by over 30% during the 1980s. Several population-based studies have concluded that most or all of this observed increase is an artifact of the lead time afforded by mammography screening rather than an indication of a true increase in the rate at which women develop the disease. We conducted a study of the social construction of breast cancer trends as a public health problem in popular U.S. magazines. We documented trends in popular magazine article coverage of breast cancer between 1980 and 1995. In addition, we analyzed the content of a convenience sample of 228 popular magazine articles published between 1987 and 1995, focusing on a subsample of articles (n = 91) that mention the increase in breast cancer incidence. Our results show that the increase in incidence is commonly portrayed as a mysterious, unexplained epidemic occurring primarily among young, professional women in their prime years. Many articles suggest that recent changes in women's behavior such as increases in delayed childbearing, nulliparity, the use of oral contraceptives, induced abortion, and the use of tobacco and alcohol are related to the recent upsurge in the disease. The portrayal of the breast cancer epidemic in the U.S. popular press reflects a strong social desire to create order and control over a frightening disease. In the process, a common message is that the behaviors and choices of young, nontraditional women especially those related to fertility control-have led to pathological repercussions within their bodies, which in turn may be responsible for great disorder and pathology at the societal level in the epidemic of breast cancer.

Motivation for eating behaviour in adolescent girls: the body beautiful.

Body dissatisfaction is commonplace for teenage girls and is associated with dieting and unhealthy weight-control behaviours. The idealisation and pursuit of thinness are seen as the main drivers of body dissatisfaction, with the media prominent in setting thin body ideals. Television and consumer magazine production in the UK are extensive, annually releasing 1x10(6) h programming and >3000 magazine titles. Their engagement by adolescent girls is high, and in surveys girls identify thin and revealing body images as influential to the appeal of thinness and their pursuit of dieting. Experimental studies show a short-term impact of these images on body dissatisfaction, especially in teenagers who are already concerned about body image. Magazine images appear more influential than television viewing. For many adolescents selecting thin-image media is purposive, permitting comparison of themselves with the models or celebrities featured. Indeed, the impact of the media needs to be understood within a social context, as engagement is often a highly-social process. Media influence is uneven because of differences in its content and manner of communication, and individual differences in vulnerability to its content. Greater social responsibility on the part of the media and better media literacy by children would be beneficial. For those working in adolescent nutrition it is a reminder that adolescent food choice and intake are subject to many competing, contradictory and non-health-related determinants.

Mammography messages in popular media: implications for patient expectations and shared clinical decision-making.

OBJECTIVE: To examine the relationship between the quantity and content of information about mammography in popular magazines and the educational level of their target audience. DESIGN: Articles published in popular magazines from January 1988 through April 1994 in which >or= 25% of all readers were females >or= 35 years of age were identified (n=65). We used the proportion of readers who were college graduates to stratify the magazines into three education levels. We used a content analysis to assess the relationship between media messages about mammography and readers' education levels. RESULTS: Seventy-eight percent of lowest education level articles were categorized as persuasive or prescriptive compared with 28% of articles in the highest education level (P < 0.01). Only 26% of the lowest education level articles that discussed screening guidelines for women under 50 years of age considered the issue controversial, while 59% of the high education level articles considered it controversial (P < 0.01). CONCLUSION: Women with lower education levels received a clearly persuasive or prescriptive message urging mammography screening, while higher educated women received more balanced and informative messages. Such differences suggest that women may be entering their physicians' offices with very different sets of information from which to draw when faced with clinical decisions. Physicians and other health-care providers should be aware of these potential differences, and further research should be done to explore the relationship between women's preferences for participation in shared decision-making and the types of messages they are receiving from popular media.

An analysis of 6 decades of hygiene-related advertising: 1940-2000.

OBJECTIVES: To describe and analyze trends in hygiene-related advertisements and examine potential social and regulatory changes that might be associated with these trends. METHODS: From 1940 to 2000, advertisements in January issues of 2 widely read magazines were analyzed every fifth year, and 2 additional magazines only available from 1960 to 2000 were also analyzed every fifth year. In a content analysis, the total number of advertisements were determined and specific advertisements were grouped into categories (personal hygiene, dishwashing, laundry, and house cleaning) and further examined for the presence of 4 key claims (aesthetics, health effects, time-saving, and microbial effects). RESULTS: From 1940 to 2000 for all magazines combined, 10.4% of the advertisements were devoted to hygiene products. After 1960 there were significantly fewer hygiene advertisements as compared with 1940 to 1955, and there was a significant increase after 1980 (P <.00001). Throughout all 6 decades, most advertisements related to personal hygiene. There were no significant differences over time in the proportion of advertisements that made claims related to health, microbial effects, or aesthetics, but significantly more advertisements before 1960 made time-savings claims (P =.009). CONCLUSIONS: This content analysis reflects a cyclical attention in consumer advertising to personal and home hygiene products during the past 6 decades, with a waning of interest in the decades from 1960 to 1980 and an apparent resurgence of advertisements from 1985 to 2000. The potential contributions of federal regulatory bodies and societal changes (e.g., new marketing strategies and options, product development, new and re-emerging infectious diseases, increasing concern about antimicrobial resistance, and increasing recognition that infectious diseases are unlikely to be eradicated) to these marketing trends are discussed.

Increased damage from rifle wounds of the chest caused by bullets striking commonly carried military equipment.

BACKGROUND: The purpose of this study was to investigate the fragmentation effect of the bullet that passes through the radio or ammunition magazine, which are essential pieces of equipment for a soldier, in thoracic gunshot injuries. METHODS: Twelve adult pigs were used. The pigs were separated into three groups (each group contained four pigs). The first group was shot without any obstacle between muzzle and subject. The second group was shot through a cartridge magazine placed in front of the subject's thoracic cage. The third group was shot with a radio in front of the subject's thoracic cage. RESULTS: It was observed that there was a large bullet entrance and fragmentation in the pigs that were shot with a radio or magazine placed over them, and there was no fragmentation in those that were shot without any obstacle. CONCLUSION: Metal equipment that soldiers carry causes bullet fragmentation. Fragmented bullets may cause excessive tissue disruption of intrathoracic vital organs.

Cigarette advertising in Mumbai, India: targeting different socioeconomic groups, women, and youth.

BACKGROUND: Despite a recent surge in tobacco advertising and the recent advertising ban (pending enforcement at the time of this study), there are few studies describing current cigarette marketing in India. This study sought to assess cigarette companies' marketing strategies in Mumbai, India. METHODS: A two week field study was conducted in Mumbai in September 2003, observing, documenting, and collecting cigarette advertising on billboards, storefronts and at point of sale along two major thoroughfares, and performing a content analysis of news, film industry, and women's magazines and three newspapers. RESULTS: Cigarette advertising was ubiquitous in the environment, present in news and in film magazines, but not in women's magazines or the newspapers. The four major advertising campaigns all associated smoking with aspiration; the premium brands targeting the higher socioeconomic status market utilised tangible images of westernization and affluence whereas the "bingo" (low priced) segment advertisements invited smokers to belong to a league of their own and "rise to the taste" using intangible images. Women were not depicted smoking, but were present in cigarette advertisements--for example, a woman almost always accompanied a man in "the man with the smooth edge" Four Square campaign. Advertisements and product placements at low heights and next to candies at point of sale were easily accessible by children. In view of the imminent enforcement of the ban on tobacco advertisements, cigarette companies are increasing advertising for the existing brand images, launching brand extensions, and brand stretching. CONCLUSION: Cigarette companies have developed sophisticated campaigns targeting men, women, and children in different socioeconomic groups. Many of these strategies circumvent the Indian tobacco advertising ban. Understanding these marketing strategies is critical to minimise the exploitation of loopholes in tobacco control legislation.
